What preparations are necessary to prevent disharmony when the tejas body goes out?

To prevent disharmony when the tejas body departs, forge an extraordinary body through dedicated hatha-yoga, for it is the vessel that must withstand the journey beyond.

— Osho
According to Osho, to prevent disharmony when the tejas (subtle) body goes out, one must forge an "extraordinary" body through long hatha-yoga preparation: asanas, mudras, and precise pranayama that stabilizes internal pressures, plus deliberate "unnatural" trainings (heat, cold, and endurance practices) to give the body iron-like resilience and a special arrangement, often requiring decades.

Train your body for years with hatha yoga, breath control, and careful heat-cold practice so it can handle your subtle energy stepping out without causing trouble.
